Short description of error
Blender is crashing when rendering with Cycles, Optix and Multilayer EXR. However, it does not crash with an older build.
I can't provide the actual file that happens with because it is a file from an ongoing project, and it is pretty big. Instead, I am attaching the crash log.

Bug seems to be caused by configuration of render output. There is good chance that you can simplify file by removing nearly all objects. Without .blend file we can't identify the bug.

Hi, looking at the crash log I think this is same as #90902 (Rendering with render region active doesn't work / crashes while saving the result)
Can you please try again with fresh builds? https://builder.blender.org/download/daily/

also fixes the crashHi
This crash does not happen during rendering. It seems to me that it happens when saving the file or when it is getting ready to save the file (after the rendering of multiple view layers are done), which is revealed by the EXR libraries in the crash log. My initial suspicion was that this was an upstream bug coming from EXR libraries. Did the EXR libraries get an update within last couple weeks? As I mentioned in the report, this type of crash does not happen with an earlier build.
I am not using the render region in this file, so most likely not related.
Hi, thanks for clarifying. Without test file it is hard to triage the report.
Did you try with the recent 3.0.0 build? :)
I don't see any recent updates to openexr or mentions in git log. Did test with simple file and I wasn't able to reproduce crash.
This still crashes with the latest nightly. I am attaching the final part of
--debug-all
The crash log is pretty much the same so not attaching it.@iss Bear in mind that these kinds of nasty bugs always show up in real life productions that deals with large assets
It seems to me that maybe the crash is happening when Blender is trying to show the rendered image back in the window.
These are the render passes. This scene has two view layers
Hi @kursadk , can you still reproduce the crash on recent builds?: https://builder.blender.org/download/daily/
